My horse hasn't shed his winter coat, possible shillings?
So as the title states I think my horse might have shillings. He hasn't shed his 3" winter coat, which in all the years I've owned him has been his longest coat, as he usually gets just a little fuzz but nothing like this. It is now June and getting really warm out, all of the other horses at the stables have shed their coat. During the beginning of winter I moved him from a 12x24 half covered pipe stall breezway to a 24x24 half covered pipe stall. I am worried that he might somehow have shillings, I've had quite a few people ask at the stables if he has it but with the expensive vet bill, I haven't had him tested but I think it's getting to the point where I might need to. He is shedding a little bit but nothing like he should be with the coat that he has. He sweats really easily when I ride or work him in the turn out but he still doesn't shed like he shold. Other people have suggested that he looks like he could possibly have cushings though he's too young at 12, and someone else also brought up thyroid issues. I don't have any pics of him yet but I'll take some next time I go to the barn. Do any of you have experience with shillings and or possibly pics of a horse with shillings so I can compare to see if it looks like what my horse has. And do you know what kind of treatment the vets use for shillings disease?
